Need an AI chat for your SME without spending weeks? This quick buying guide helps you compare options, set a budget, ensure compliance, and launch in days, not months.
You need to choose an AI chat online for your SME without spending weeks on it. This quick buying guide helps you compare options, define the budget, verify compliance, and go into production in a few days, not months.
Before diving in, if you want to validate the highest-yielding use cases first, check out our dedicated article on chatbots for SMEs, use cases that pay off.
Depending on your context, "AI chat online" can refer to three complementary families:
Assistance chat on your site: answers product, policy, and delivery questions, and captures leads.
Support chat connected to your helpdesk: handles recurring tickets, proposes actions, and escalates to a human agent.
Sales/qualification chat: asks the right questions, enriches the CRM, books a slot in the sales calendar.
Behind the term chatbot, many now speak of AI agents, capable of observing context, deciding, and acting—for example, creating a ticket, updating a CRM, or triggering a refund under supervision.
Intent coverage: the assistant must answer precisely based on your content and procedures, not just generic FAQs.
Frictionless human handoff: clear button to speak to an advisor, transfer with history, managed hours and queues.
Useful native integrations: CRM, e-commerce, helpdesk, analytics. Prioritize connectors that already exist in your stack.
GDPR and security: EU hosting available, encryption, configurable retention duration, data processing agreement, and strict access rights. To go further, the CNIL details best practices around conversational assistants and personal data.
Predictable cost: avoid opaque pricing. Understand the billing unit—conversation, message, token, seat—and the tiers.
Quality of experience: low latency (1 to 3 seconds), controllable tone, verifiable answers, sources cited if possible.
Measurement and steering: conversation analytics, intent tags, self-resolution rates, continuous improvement loops.
To distinguish marketing from reality, use our evaluation method with 20 questions from your tickets and emails. Score each solution on accuracy, security, and experience, then pick the best overall score, not the best demo.
Option | Implementation Time | Typical Monthly Cost | For Whom | Limits |
|---|---|---|---|---|
Plug-and-play SaaS | 1 to 3 days | €30 to €300 | Small teams, rapid need | Customization and integrations sometimes limited |
No-code Builder | 3 to 10 days | €200 to €800 | SMEs wanting flow control | Safeguards and debugging sometimes basic |
Managed Open Source Stack | 2 to 4 weeks | €100 to €500 (infra, excl. setup) | Tech teams, data/EU constraints | Maintenance and MLOps to be expected |
Custom with Agency | 2 to 8 weeks | €500 to €2,000 (ops, excl. dev) | Critical ROI cases, complex integrations | Requires an experienced partner |
Indicative amounts, varying by volume, integrations, and SLA.
If you are hesitating between a prototype and a full build, our overview of online AI platforms to test for rapid prototyping can help you choose the right testing ground.
Sum up four items for a realistic estimate:
Software license: monthly plan plus options.
Consumption: based on messages, conversations, or API usage.
Integrations and data: connectors, knowledge base synchronization, hosting costs if necessary.
Setup and improvement: a few days to a few weeks depending on complexity, then a small continuous improvement retainer.
Indicative example: 1,000 conversations/month, 50% self-resolved, average internal cost per ticket €7: potential gross gains €3,500/month. If your license + consumption + monitoring combination costs you €400/month, with an amortized integration budget of €250/month and €150/month for improvements, the net margin remains very positive, as long as the response quality keeps its promises.
To secure this promise, rely on measurements, not intuition. We detail the implementation of conversational KPIs in our article AI KPIs, measuring the impact on your business.
Hosting and localization: EU option available, data export and deletion on demand.
GDPR/DPA contract and listed subprocessors: no retraining on your data without consent.
Encryption in transit and at rest, key management, audit logs.
Roles and access: SSO if possible, partitioning by team and environment.
PII filtering and masking: automatic redaction of sensitive numbers.
Protection against prompt injection and information leakage: guardrails, tool allow-lists, context limits.
The CNIL publishes practical guidelines on assistants and personal data, useful for framing your choices (see cnil.fr, Conversational Assistant and Personal Data).
For advanced uses linking chat to internal documents, follow the RAG best practices detailed in "Robust RAG in production, best practices and evaluation" and the integration models described in AI APIs, clean and secure integration models.
E-commerce: CMS and product catalog, stock management, orders and delivery status, wishlist generation, redirect to cart.
B2B/Service: CRM, qualification, scoring, appointment booking, company and contact enrichment.
Support: helpdesk and knowledge base, ticket creation and updates, resolution macros.
Internal: HRIS and ITSM, HR questions, internal policies, access requests, passwords, with restricted access.
Start with two integrations that cover 80% of the priority 1 flow, then expand.
Criterion | Weighting | How to verify |
|---|---|---|
Understanding your data | 20% | 20 real questions, score accuracy and sources |
Effective human handoff | 15% | Request transfer, check history and context |
Latency | 10% | Measure average response time and p95 |
Predictable cost | 15% | Simulate 1,000 conversations, validate tiers |
Security/GDPR | 20% | Request DPA, EU hosting, configurable retention |
Key integrations | 10% | Test at least one critical connector |
Analytics and improvement | 10% | Check intent tagging, feedback, export |
Total out of 100. Only buy if the solution exceeds 70/100 on your real data.
Scoping: top 20 intents, objectives, KPIs, guardrails.
Data: connect your knowledge base and policies, clean up documents.
Persona and tone: define style, language, non-response policy.
Handshake flow: handoff to human, hours, escalation rules.
Priority integrations: CRM or helpdesk, one at a time.
Testing: real scenarios, red teaming, attack prompts, and edge cases.
Analytics: intent tagging, dashboards, feedback loops.
Team training: human takeover script, simple legal guidelines.
Progressive Go-live: on one page or segment, monitor latency and quality.
Adjustments: correcting contentious answers, adding intents, gradual expansion.
Where is data hosted and what is the configurable retention period at the client level?
Do you offer a GDPR-compliant DPA, and the deactivation of training on my data?
What native connectors do you have for my CRM/helpdesk, and how do you handle custom fields?
How can I control tone, refusals, and source citations?
What is your billing model and what are the overage tiers?
What is the average response time and p95 latency during peak hours?
How does the handoff to a human agent work, including context transfer?
What protections do you offer against prompt injection and information leakage?
What analytics metrics and exports do you provide, in real-time and batch?
Do you provide access to a test environment and an integration sandbox?
Launching without clean data: the tool will give hollow answers, then be abandoned.
Forgetting human escalation: a good AI chat online must know when to stay silent and hand over.
Ignoring measurement: without KPIs, it's impossible to prove ROI or improve.
Underestimating compliance: better a cautious and traceable answer than a brilliant but risky one.
